Factor out common factors: Look for common factors in pairs of terms.First, we look at the first two terms, 7q3 and −14q2, and factor out the greatest common factor, which is 7q2.7q3−14q2=7q2(q−2)
Factor remaining terms: Look for common factors in the remaining pair of terms.Next, we look at the last two terms, −5q and +10, and factor out the greatest common factor, which is −5.−5q+10=−5(q−2)
Write down findings: Write down what we have found so far.We have factored the polynomial into two parts:7q3−14q2=7q2(q−2)−5q+10=−5(q−2)Now, we can write the polynomial as:7q2(q−2)−5(q−2)
Factor out common binomial: Factor out the common binomial factor.We notice that (q−2) is a common factor in both terms. We can factor this out:7q2(q−2)−5(q−2)=(q−2)(7q2−5)
Check quadratic factor: Check if the quadratic factor can be factored further.The quadratic factor 7q2−5 does not have any common factors and cannot be factored further using integers. Therefore, the factored form of the polynomial is:(q−2)(7q2−5)
